Nuclear Medicine - Bone Marrow
What is Bone Marrow Imaging?
Bone Marrow Imaging is a diagnostic study used to evaluate bone marrow activity in multiple diseases or in bone marrow replacement.
- Marrow involvement in infection (99mTc-Sunfur Colloid)
- Marrow involvement in Metastatic Disease (99mTc-HMPAO/WBC)
- Aplastic Anemia (11-In-Chloride)
- Myelofibrosis (111-In-Chloride)
- Marrow viability post transplant or Radiotherapy (99mTc-HMPAO/WBC)
How do I prep for this procedure
There is no preparation required for this procedure.
What should a patient expect of the procedure?
- Time in the department is depended on the type of exam being performed.
- Infection, 99mTc-SC and 111In-WBC you will return to the department multiple times
- It will take 5 –10 minutes for a Nuclear Medicine technologist to withdraw 60cc of blood (via a hep-loc) in order to separate your white blood cells from the red and be tagged to an isotope.
- You will return 4 hours later to be injected with your WBC which will take 5-8 minutes
- You will return 4 hours after injection so the first image can be made, taking 30-50 minutes
- You will return 24 hours later for the second image to be made, taking 35-50 minutes
- You will receive another isotope (99mTc-SC) and wait 30 minutes before taking an image
- You may be imaged for 35-50 minutes using both isotope peak or 1 peak for 15-25 minutes then the other for 15-25
- This could be repeated 48 hours later
- Metastatic involvement and Marrow Viability, 99mTc-HMPAO/WBC – you will return to the department multiple times
- It will take 5-10 minutes for the technologist to withdraw 60cc of blood (via hep-loc) in order to separate your WBC from your RBC and tag to the isotope
- You will return 4 hours later to be injected with your WBC taking 5-8 minutes
- You will return 2 hours after injection for first imaging which will take 20-45
- You will return 2 hours after the first image to take the second image which will take 20-45 minutes
- This could be repeated 24 hours later
- Aplastic Anemia and Myelofibrosis, 111In-CL- you will return to the department multiple times
- It will take 3-5 minutes for a technologist to inject you with the isotope
- You will return 24 hours after your injection for the first image which will take from 35-50 minutes
- You will return again 48 hours from the injection for the second image, which will take 35-50 minutes
- This could be repeated 72 hours after injection and 96 hours after injection.
